IMPROVEMENT IN ME'SURING-FUNNELS.

Specification form'in g part of Letters Patent No. 174,823, dated March14, 18.76

June 8, 1874.

To all whom it may conce-ru Beit known that I, DANIEL S. KooNs, ofChicago, in the county of Cook and State of Illinois, have invented anew and useful Measuring-Funnel, of which the following is aspecification rIhe nature of this invention relates to an improvement inthat class of funnels which are ttted with valves to hold the liquiduntil a given quantity is filled in, indicated by lilies or zones on theinverted cone, and then discharged by opening the valve. The inventionconsists in the peculiar fastening ofthe thumblever and valve-rod; and,further, in the combination of the valve-rod, the valve, and the hingedstrainer, for the purpose ot' removing the rod and valve withoutremoving the strainer.

Figure 1 is a perspectiveview of the funnel, with a portion of the wallbroken out to show the hinged strainer. Fig. 2 is a vertical section ata' x. Fig. 3 is a sectional detail of the lever'and valve-rod unccupled.

In the drawing, A represents the body of my funnel, having at its lowerend a tapering discharge-spout, A1, which is made doublewalled byaninternal shell, A2. In the lower part of the spout A1 a row of holes, a,is made, and near the top another row, a. The air expelled from a vesselbeing filled passes into the space between the double walls through theholes a, and out through the holes a. Bis the handle7 and on top, nearthe edge of the funnel, is erected a standard, b, to which is pivoted athumb-lever, C, With a spiral spring underneath it, to depress the innerend. I) is a valve-rod, having a hook, d, at its upper end, whichengages with the transverse stud c of the lever, in the manner shown inFig. 3, so thatit can be readily de- -tached whenever it becomesnecessary to remove the valve or to clean the funnel.

. a valve, having its seat in the apex of the fun- Eisl ; applicationiiled nel, its stem being guided by passing through l to permit the rodto play freely. Being in the4 lower part of the funnel, it serves toremove or rather to prevent foreign substances to pass with the liquidthrough the spout, and also, by being hinged to the funnel, allows thevalverod and valve to be-removed Without removing such strainer, therebychanging the funnel into a common funnel, with a strainer bottom. Therings or beads f spun into the walls of the funnel, serveas graduates toindicate the various quantities of liquid to be measured by the funnel,the closed valve retaining them until so -measured and ready to bedischarged. The valve-rod is curved to conform to the outline of thefunnel, as shown.

What I claim as my invention, and desire to secure by Letters Patent,is-

l. The combination, in a funnel, of the thumb-lever C provided with thestud c and the valve-rod D, having the hook d, when the several partsare constructed and arranged substantially as described, for the purposeof having the parts pivoted together so 'as to be convenientlyseparated.

2. The combination, in a funnel,ot` the removable valverod D, theremovable valve E, and the hinged strainer G, When the several parts areconstructed and arranged, substantially as described, for the purpose ofhaving the valve and valve-rod easily removed without removing thestrainer.
